Sumario:A search is presented for heavy resonances decaying into a Z boson and either a W boson or another Z boson (WZ or ZZ), with one Z boson decaying into a pair of neutrinos and the other boson decaying hadronically into a pair of collimated quarks, which is reconstructed as a highly energetic boosted jet. The search is performed using the data collected by the CMS detector at the CERN LHC during 2016 in proton-proton collisions at a center-of-mass energy of $13~\mathrm{TeV}$, corresponding to a total integrated luminosity of $35.9~\mathrm{fb}^{-1}$. No excess is observed in data with regards to background expectations. Results are interpreted in beyond standard model scenarios. Limits on production cross sections are set in the range 0.8--50$~\mathrm{fb}$ for spin-2 bulk gravitons and for W' bosons in the context of the heavy vector triplet (HVT) model. For the two HVT scenarios considered, a W' resonance is excluded at $95\%~\mathrm{CL}$ up to a mass of $3.2~\mathrm{TeV}$ in the first case and $3.5~\mathrm{TeV}$ in the second.
